using clang++ : how do you compile a program with multiple files

[gdo...@gmail.com]

given three files

GradeBook.h
GradeBook.cpp
fig03_15.cpp -- which contains main --

how do i compile this to produce and object file,
an executable, with the name fig03_15?

-----------------------------

i tried:

clang++ -o fig03_13 GradeBook.h GradeBook.cpp fig03_13.cpp

clang++ GradeBook.h GradeBook.cpp fig03_13.cpp -o fig03_13

i get:

clang: error: cannot specify -o when generating multiple output files


------------------------------
also:

clang++ GradeBook.h GradeBook.cpp fig03_13.cpp

produces an a.out that works and it produces a file named
GradeBook.h.gch


Thanks everyone,

Your teacher should have explained.

clang++ -o fig03_13 GradeBook.cpp fig03_13.cpp
clang++ GradeBook.cpp fig03_13.cpp -o fig03_13

ought to do it. That's your lines, but without the .h file.

Inside the cpp files you'll find a line
#include "GradeBook.h"
which is how it gets used.
